Properties of Water Introduction: Water’s chemical description is H2O. As the diagram to the left shows‚ that is one atom of oxygen bound to two atoms of hydrogen. The hydrogen atoms are "attached" to one side of the oxygen atom‚ resulting in a water molecule having a positive charge on the side where the hydrogen atoms are and a negative charge on the other side‚ where the oxygen atom is. This uneven distribution of charge is called polarity. Since opposite electrical charges attract‚ water molecules

Pond Water Paper DIRECTIONS STYLE TENSE: In all sections of the paper‚ present tense should be used to report background that is already established. For example‚ "The cell membrane is the barrier which separates the inside of the cell from the outside." Use future tense for work that you will do. For example‚ "This experiment will test the hypothesis that some anti-microbial agents can permeate the cell membrane during division to inhibit growth." Use past tense to describe the methods (what

Properties of Water Lab # 1 Biology 111 January 23‚ 2011 INTRODUCTION With surface tension it is made possible for items such as paper clips to float on water‚ because a molecule within the mass of a liquid encounters gravity to all adjacent molecules in all directions. When you use surfactant substances this creates hydrogen bonds. Purpose of experiment 1 will be to show that once the surfactant substances hits the hydrogen bond pulls down paper clips. Things

Ecology Essay Water makes up 75% of your body and is absolutely necessary for living. But do we know what we are drinking when we drink bottled‚ Recycled‚ and tap water? You might think it really does not matter‚ i mean they are all the same clean water right? Well‚ according to Rebecca Ephriham water that individuals and our families drink could contain deadly toxins‚ and can even cause cancer and other life threatening diseases. Some water is much cleaner than others and a much better choice for

They are not only marketing for the rich and/or famous‚ they want to be an everyday thirst quencher. Perrier vision is to be the number one sparkling mineral water in the world. Perrier’s mission is to offer bottled water to meet consumer needs anywhere‚ anytime. In May of 1989 in an issue of Fortune the company was depicted as one of six companies

Wine to Water Not having a purpose in life or not knowing what to do or where to go might just be the worst feeling to have. I believe everyone has a purpose‚ something we were meant to do or be good at. Finding that one thing is just the hard part. The book Wine to Water shows us a story about a guy that really doesn’t get why he’s here. What his purpose really is until he finds out the worlds crisis for water and how he can actually help these people. Being in college‚ Just graduating from

how hydrogen bonding occurs between water molecules‚ and relate this and other properties of water‚ to the roles of water in living organisms. Water is a very small molecule‚ consisting of two hydrogen atoms covalently bonded to an oxygen atom. However the electrons shared are not done so equally‚ oxygen is more electronegative and has a firmer hold on the electrons and pulls them slightly towards its nucleus. Due to this‚ the charge across the molecule of water is not equally distributed‚ and the

Water is determined by the amounts and kind of suspended and dissolved substances in the water‚ degree of alkalinity (pH)‚ temperature‚ colour and smell‚ and the company of undesirable microorganisms. In this experiment‚ we are explaining whether bottled water is more pure than tap water. For this experiment‚ hypothesis is which water is more pure bottled or taps water. To test the experiment we have used the equipment like bottled water‚ tap water and water test kit. In the research‚ it has been

Water Shortages Water has been one of our natural resources that we have used throughout time in many different ways. We have developed ways to make it more available and use it to create energy. However‚ because we have made it more available‚ we have developed issues that waste our good clean water‚ take old pipes that have been used to transport water across cities for example. Because they are so old‚ they tend to waste about 7 billion gallons of water every day (CQ Report‚ 2010‚ p.531). And

Hot water And Cold Water Advantages and Disadvantages The main purpose of drinking any liquid‚ water in particular‚ is to hydrate our body. Either hot or cold water will serve this purpose. Obviously‚ cold water sounds more tempting than hot water. There is some evidence to suggest you can benefit from some extra calories being burned by drinking cold water. The body has to regulate its temperature to around 98.6 degrees. Drinking cold water forces the body to work a little harder to bring the temperature
